IMPRovEMENr IN ALcoHoL-STILLS.

The Schedule referred t in these Letters Patent and making part of the same.

Beit known that I, GEORGE CLARKSQN, of the city of Elgin, in the county of Kane in the State of Illinois, have invented a new and useful Machine and Apparatus i'or the Manufacture of Alcohol by process of continuous distillation from the mash or grain, and for the prevention of frauds upon the revenue in the manufacture of distilled spirits, entitled Olarimous Continuous Alcohol-Still, and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing.

Figure l is a side elevation of my invention.

Figure 2 is a vertical central section.

Figure 3 is a detail showing the worm.

A represents a receiver of cylindrical shape. It is dividedl into unequal portions by a diaphragm, `and uear/the-eenter are openings for allowing the two portions to communicate by means of a pipe.

' '.lhe lower portion contains a steam-coil, (t, colu-V mencin'g at bfaud terminating at c.A

These sections or portions are provided with flanges d, which are secured together by bolts and nuts.

The receiver is attached to the worm of a grain-still by means ofthe pipe c, which receives the high-wines to be distilled from the tub, and passes the same through the chamber B and regulating-faucet D to the lower chamber C.

The oice of the faucet D is to regulate the necessary flow of wines from the chamber B to chamber C through the pipes f.

'.lhe wincsbeing thus introduced into lthe lower chamber, are subjected to a steam pressure ii'om the steam-pipe b in the coil a suiiicient to couuterbalan ce the pressure in the alcohol-still.

The pressure is governed bythe steam-gauge E, as shown in the drawing. This steam-gauge is secured to the upper end of chamber G.

t Ihe steam islet into the chamber at b', passing through the coil a, from whence it passes ofi' through the pipe c. g

The wine is thus exposed to the action of' the steam constantly passing through the coil in chamber O, and

in this manner .its alcohol is abstracted.

When the alcohol has been separated from the highwines in the reservoir, the residnum is carried through the pipe h. p

F F represent glass gauge-tubes, secured at their ends upon the sides of the chambers B and C, to show the altitude of the fluid in each chamber.

H H represent ordinary steam-valves, secured to the chambers B and O, as shown in the drawing, to let o the surplus steam, when the steam-gauge on 'chamber O, indicates a higher pressure than is shown by the steam-gauge ou the alcohol-still vacuum.

' K represents a safety-valve att-ached to chamber C, as shown on the'drawing at t. The object cfthis valve is to avoid excessive pressure of steam in said chamber.v

The operation oi' my device is as follows:

The high-wineas it descends from the worm accumulates in the upper chamber B until that chamber becomes nearly filled, which, when the attendant perceives by inspection of the glass tubes, he opens the regulating-faucet D of the pipe c and discharges the content-s into the lower chamber O, then shutting the valve, when the wine again 'accumulates in B, and

when it is a second time nearly full, the contents of" the lower chamberO are discharged through the lower cock and pipe, and again the charge in the chamber I3 is let down, and thus the process goes on.

` What I claim as new, and desire to secure by Letters Patent, is-

l. rIhe stiil herein described, having compartments B audO, constructed and arranged substantially as specified. 2. Incombination with a double-chambered still, the pipes c, h, and f, valve K, and regulating-faucet D, substantially as specified.

3. The coiled pipe a, induction-pipe b and eductionpipe c, in combination with the double-chambered still,

substantially as specified.

4. In combination with a double-chambered still constructed for continuous distillation, the glass gauges Fand F', constructed and arranged substantially aS described.

Witnessess GEORGE CLARKSON.
